2 Claims. 1

This invention relates to cookers, and particularly to those employed in the confectionery industry for cooking or heating syrups and other fluids.

One of the objects of the invention is to provide in an apparatus of this character, means by which the flow of the fluids through the coils is accelerated so that the frictional contact of the syrup with the passages through the coils is decreased; of means by which the feeding of the syrup into the coils is facilitated and a constant flow of the syrup through the coils is insured, and of means by which the egress of the cooked or heated syrup from the coils is expedited.

The invention further contemplates the provision of a plurality of coils, preferably but not necessarily concentrically arranged and adapted to have their upper ends or terminals received in a coupling or manifold member located at the top of the cooker, said coupling or manifold member being provided with a single entrance passage through which the fluid to be heated is passed to become distributed into the. several coils through which the same flows to then emerge at the lower end of the cooker and pass out of a coupling or manifold member similar in general construction to that provided at the upper ends of the coils.

These and other objects are attained by the invention, a more particular description of which will hereinafter appear and be set forth in the claims appended hereto.

' In the accompanying drawings, wherein an illustrative embodimentv of the invention is disclosed, Fig. l is vertical sectional view through parts of a cooker of the character described, showing the present improvements; Fig 2 is a top plan view of the two concentrically-arranged coils through which the materials to be heated are passed, showing the upper and lower couplings or manifold members attached to the respective ends of the coils; Fig. 3 is a sectional view through the upper coupling or manifold member; Fig. 4 is a sectional view through the lower coupling or manifold, and Fig. 5 is a top plan view of the lower coupling or manifold member.

With reference to the drawings, l indicates the body or casing of the cooker, the same constituting a steam chamber and which, in the form shown, is of generally cylindrical shape provided with a domed upper closure or top 2. At its lower end the body or casting I is provided with a radial flange 3 by means of which it is supported upon a suitable structure, including a 2 7 table member 4 and legs or pedestals 5. The in.- terior of the body or casing i is supplied with a heating medium, such as steam, in the known manner, and coils contained within the body or casing of the cooker constitute spiral or helical passagesthrough which the material to be cooked or heated is conveyed.

In the present embodiment of the invention, two of such coils are shown, the same. being re,- spectively indicated at 6 and I, that shown at 6 being the inner coil and that shown at i being the outer coil which is arranged concentrically about the inner coil.

The two coils 6 and I are maintained in the spaced, concentric manner shown and described, by means of the vertically disposed supporting bars 8 and 9, said bars serving to maintain the convolutions of the coils in spaced relation to allow the steam to pass between the same.

The inner coil is provided with an upper end or terminal I0, while the outer coil 1 has a similar upper end or terminal ll, and these two upper ends or terminals of the two coils are received in a suitable coupling member or manifold l2 secured in the top 2 of the casing or body of the cooker. The coupling or manifold member l2, constituting an inlet to the two coils for the material to be cooked, is in the form of a disk provided centrally at the top with a tubular extension or nipple I3 to which is suitably coupled at [4, a goose-neck inlet pipe I5 through which the material to be cooked is fed to thereby pass through the couplingor manifold member I 2 and be distributed thereby into the two coils 6 and 1.

The tubular extension or nipple I3, projecting from the coupling or manifold member 12 is in communication with the two passages 16 and I! that extend divergently from the center of the manifold to the edge thereof, said passages connecting respectively to the upper ends II and HI of the coils l and 6. This arrangement is such that a single feed pipe, indicated at I5, is in .communication by means of the coupling or manifold member I2, with the two upper ends I U and l l of the two coils 6 and l, and the fluid-materials to be heated, entering through the pipe I5, will fiowequickly and uninterruptedly down through the two coils 6 and 1.

To accommodate the coupling or manifold member l2, the top 2 of the casing or body of the cooker is provided with an opening surrounded and reinforced by the annulus I1, and the outer face of the reinforcing annulus ll serves as a seat for a clamping ring l8, through which a plurality of screws pass, said screws being thread- 3 ably received in the body of the coupling or manifold member (2, as clearly shown in Fig. 3. Through this arrangement it will be apparent that the annulus I1 is firmly clamped between the coupling or manifold member l2 and the clamping ring i8 and the coupling or manifold is thus securely fitted and held in place while receiving and supporting the upper ends of the two coils 6 and 7. A gasket 28 is interposed between the upper face of the coupling or manifold member 12 and the inner face of the annulus I! to prevent steam leakage at this point. For strength and reinforcing purposes, the member l2 may be provided with webs 25a. 7

The lower manifold or outlet member 25, to which the lower ends 2! and. 22 of the coils 6 and l are connected is similar in shape and construction to the inlet manifold 12, and said outlet member includes the central outlet tube or pipe 23 having its upper end in communication with the radially extending divergent passages 2d and 26 extending through the outlet member. The passage 24 is coupled to the end 21 of the outer coil 7, while the passage 25 is shown as being coupled to the lower end 22 of the inner coil 6. This arrangement is such that the fluid flowing through the two coils will merge within the outlet member 25 and will flow downwardly and out of the outlet member 25 through the outlet tube or pipe 23 to descend into suitable kettles or other receptacle provided below the bottom 4 of the cooker.

The outlet member 25 is mounted in an aperture 27 in the bottom 4 of the cooker and is held in position thereover by means of a clamping ring 28 through which screws 29 are extended to threadably enter the outlet member 25 as clearly seen in Fig. 4. A gasket 30 is interposed between the lower face of the member 25 and the upper face of the bottom 4 to prevent steam leakage at this point.

By means of the arrangement described, the syrup or other fluid to be heated, enters at the top of the cooker through the delivery pipe to pass down through the inlet manifold l2 and be distributed into the two coils 6 and l. The descent of the fluid through the coils is rapid and takes place with a minimum of friction and the descending fluid is rapidly heated by the steam surrounding the coils.

At the lower ends of the two coils 6 and I, the cooked or heated syrup merges in the outlet member 25 and descends through the outlet pipe 23 into a suitable kettle located below said pipe. The arrangement disclosed is such that the coils and manifold members at the opposite ends of the same may be quickly assembled and the unit speedily located within the cooker and the manifold members clamped in position by the insertion of the screws 49 and 29. The operation of the arrangement disclosed will be found highly effective for the production of an improved texture, smooth and wholly satisfactory syrup or similar product. a

Having described one embodiment of the invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the claims appended hereto. For example, while I have herein described the coils as being concentrically arranged, it will be obvious that they may be otherwise disposed. Also while I have herein shown the coils as being two in number, this number may be increased. These and other modifications are obvious to those skilled in this art and are considered as being comprehended by the present invention.

What I claim is:

1. In a cooker of the character described, a coupling for the ends of a pair of fluid-conveying coils, said coupling consisting of a disk having a central inlet passage, a pipe connected to said passage, said coupling having a pair of passages in communication with one end of the central passage and extending divergently from the cen tral passage to the edge of the coupling, a pair of concentric coils having their ends respectively connected to the ends of the divergent passages, a cooker having a top provided with an aperture, an annulus fitted in said aperture, the coupling being disposed against a face of the annulus, and clamping means for holding the coupling against said face of the annulus, said clamping means including a ring disposed against the opposite face of the annulus, and threadable fastening elements extending through the aperture in the annulus and passing through the ring and threadably received in the coupling, said ring and coupling being attached to said annulus solely by clamping pressure imposed on it between the coupling and ring.

2. In a cooker of the character described, a cooker body having an opening, a coupling body in the form of a disk having a central passage in the form of a tube entering axially into the disk, the disk being provided with a pair of passages extending divergently from the central passage and substantially at right angles thereto, a pair of coils having ends respectively connected to the ends of said divergent passages, the coupling disk having a gasketed face resting against the surface of the cooker body and surrounding the opening therein, a clamping ring fitted against the opposite face of the body and surrounding the opening, and clamping screws extending through the opening in the cooker body and threadably entering the body of the coupling, the coupling and clamping ring being held on the cooker body solely by the clamping pressure. imposed by the screws to clamp the cooker body between said coupling and ring.
